I fail to see those undertones of paedophilia or fetishism. Incest by misinterpretation, but again Trish is Trish and Dante knows and recognizes that. He doesn't project Eva on to Trish so even if he did have sex with her its not incestuous at all.

Nothing needs to be rewritten. I've seen fanfics and hentai of every character engaging in incest. Most DMC hentai is DanteXVergil, so it really doesn't matter how the story is written, these pairings will happen.
